This invention relates to insulated `building conmetal plates,insulating material positioned on the metal plates in nat face contacttherewith, and means attached to thev clamp members for retaining theinsulating material on the metal plates.

"Many unsuccessful attempts have been, made i previously for providingmeans toretain andsupport insulating material, such as mineral woolbats,*in position on the inside surface of building structures made ofVplain orv corrugatedsh'eet metal,` such as by adhering thebats byadhesive or by applying an outer retaining sheath.. Such methods arecostly, cumbersome and do not provide secure retaining means which willinsure retention of the insulating materialand permit removal of samewhen necessary, especially in the oase of temporary metal .buildingstructures.

According to the present invention the retaining means for theinsulating material are simple in construction and can be readilyapplied so as to securely retain the insulating material on the metalstructural elements. y

Other objects and advantages of the invention may be apparent to thoseskilled in the art from the following detailed description of what arenow considered to be the preferred embodiments of the invention.

Referring to the drawings:

Figure l is a plan view of the interior surface of a metal buildingconstruction showing bats of insulating material retained thereon inaccordance with the present invention,

Figure 2 is a sectional view taken on lines 2 2 of Figure 1,

Figure 3 is a view, partly in section, taken on lines 3-3 of Figure 2, f

Figure 4 is a perspective view of one form of a clip member,

Figure 5 is a sectional view similar to Figure 2 showing theuse of amodified clip construction,

Figure 6 is a perspective View of a modified clip member used in theconstruction of Figure 5, and

Figure 7 is a perspective view of a retaining element for retaining theinsulating material.

Referring to the drawings, Figures 1 and 2 disclose a metal buildingconstruction made of v2 A- smooth or corrugated metalplates Ill,fastened together by suitably spaced threaded bolts I'I at theiroverlappedA marginalportions'and securely lockedby nuts I2.' Inthe usualmetal buildingr construction thesebolts I I extend toward the in-"terior of the building construction. AClamp members'I are providedhaving the construction lshown in Figurefl inorder to retain the bats ofinsulating material I5 on the surface of the metal plates Ill. Theseclamp members are made of flat flexible metal strips, preferably ofsteel,`which are bent into the contour shown inFigure 4 soy as toprovide a 'reversely bent end' consisting' of U-shaped leg portions I8and I'I and an upwardly extending member 2I having one or `more spacedapertures 22 for a purpose 'to be explained later. The leg portions I8and Il `areprovided with aligned apertures I9 and 20, respectively, toper- K 4'mit the'clamp member to be slipped over the free end' of boltsII, as shown'in Figures 2l andA 3. The leg members I7 and I8 arepositioned atan acute angle to each other, less than 4:5",r andv areslightlycompressed v-or moved toward each other f when applied to thebolt I Iso that when released l, the leg portions normally rtend tospread apart.

This resulting tension lcauses the inner perimeter of the apertures I9and 20 'to engage and wedge between the threads of the bolt I I and thusfirmly retain the clamp member I5 on the bolt Il.

As shown in Figures 1 and 2, a plurality of spaced'clamp members IS arepositioned on the spaced bolts II used for fastening the metal sheets I0of the building construction. Bats of insulating material I5 are thenapplied in flat face contact with thesurfaces of the metal plates and asufficient number of fastening members 25 are then inserted in theapertures 22 so as t0 extend between pairs of clamp members, as shown inFigures 1 and 2, to retain the insulating bats I5 on the metal platesI0. The retaining members 25 are made of stiff metal rods or Wireshaving bent pointed ends 26 for facilitating their insertion into theapertures 22.V It is to be understood that other retaining means for theinsulating material may be usedsuch as'bands, Wire, string, etc., whichmay be fastened to the clamp membersI in any suitable manner.

The invention is not restricted to the specific clampmember'construction shown in Figure 4. For example, another suitableclamp member construction is shown in Figure 6 which is made l of a flatmetal strip bent upon itself to provide Wedge between threads of bolt II, thereby rmly retaining the clamp member on the bolt. A plurality ofsuch clamp members are used to provide a sufficient number of spacedmembers forreceivng retaining membersy 25 or other retaining meansreceiving in apertures 32 of the clamp members for retaining theinsulating material securely on the metal plates I 0. i

It will be apparent from the foregoing description that a very emcient,economical and simple means is provided for retaining insulatingmaterialon metalv building constructions.` The clamp members andfastening elements can be applied `by unskilled labor asno experience ortraining is required to perform the operation. No tools;are necessary`because the clamp members are applied manually by simply slipping themon the bolts and retaining elements are supplied of suitable dimensionsso that they are simply inserted in the .apertures of the clamp members.Bats of. insulating material can then be applied very. rapidly and withextremely little labor. The ba-ts. of insulating material are securelyretained Yon ythe metal plates and will not sag or fall o. The bats-*canalso be easily removed in event of needed dismantling of the structurebecause the fastening ,elements and clamp members can be readily removedmanually without requiring any tools by simply disengaging the clampfrom the boltv and slipping it oli.

It is to be understood -that numerous modications .and changes may be-made in the present construction embodying theessential and significantfeatures of this invention which are intended to be covered by theappended claim.

We claim:

A buildingl structure comprising a plurality of metal plates fastenedtogether by a plurality of spaced threaded bolts, said bolts extendingbeyond one face of said plates, spring clamp members frictionallyretained on said spaced bolts and extending outwardly of said face ofsaid metal plates, each of said spring clamp members comprisingV avrnet'alfstrip reversely' bent at one end thereof to provide U-shapedleg members, aligned apertures in said .leg members frictionallyengaging said bolts adjacent said metal plates, and the other end ofsaid strip provided with retaining apertures for receiving wire rodstherein, insulating material positioned on said metal plates in flatface contact with said face of said plates and covering said U-shapedleg members of said spring clamp members, and wire rods received in theretaining apertures of said clamp members and retaining the insulatingmaterial on said metal plates, said wire rods being of a length toextend between-said spaced clamp members.
